Hospital del Mar is a modern general hospital that treats medium and high complexity pathologies. It is also research-based and affiliated with a university. The hospital has a long history of service to the city and continues to grow and adapt to meet the needs of its diverse population. Due to its location by the sea, architecturally unique, and flooded with Mediterranean light, the hospital seems to mimic its reference population in Ciutat Vella and Sant Martí districts. This population is exceptionally heterogeneous and multicultural and works to adapt to the changes it demands. The Hospital del Mar is a professional, efficient and productive healthcare facility that collaborates with various health networks and devices in the city. While it primarily focuses on providing medical assistance, it also has a strong connection with research through the Hospital del Mar Research Institute. Despite its small size, the hospital has made significant scientific contributions through projects that aim to apply science to improve the health of its patients.
